First off, let me say this filter is a solid alternative to the pricey Dyson originals. It fits perfectly in my TP04, and the air quality readings are just as good as before.

Installation was a bit tricky at first—especially the carbon filter. Pro tip: hook one side in first and slightly flex it open to get the other side in. Don’t force it straight on or you’ll bend the hooks (learned that the hard way).

The HEPA layer feels sturdy, and I haven’t noticed any weird odors sneaking through. My only gripe? The carbon filter is a bit noisier than Dyson’s—you can hear tiny particles shifting inside like sand. Not a dealbreaker, but noticeable.

For the price, it’s a steal compared to OEM filters. Just double-check your model number before buying—this won’t fit newer Dyson units like HP07 or TP07. Also, don’t forget to reset both filters separately after installing (hold ‘Oscillation’ for HEPA, ‘Night mode’ for carbon).

Verdict: 8/10. Works great if installed right, but lacks some finesse of the original.
